Gigabyte EP45-UD3P Rev 1.6 BIOS FD with Dual Video Cards

[digdugbug]

I replaced the motherboard in my hack from an ASUS to a GA EP45-UD3P Rev 1.6 FD and needed to get dual video cards working.

 

The following notes should help you if you have the same motherboard and video cards that are close in specs.

 

• GA EP45 UD3P Rev 1.6 BIOS FD
  
• 512 MB 8800 GT in slot 1 (x16)
  
• 256 MB 8800 GT in slot 2 (x8)
  

 

 

The first slot has has a pci address of PciRoot(0x1)/Pci(0x1,0x0)/Pci(0x0,0x0) while the second slot is PciRoot(0x1)/Pci(0x6,0x0)/Pci(0x0,0x0)

• set display to PEG not PEG2
  
• modifed DSDT.aml only for RTC fix
